Re: [EnergyPlus_Support] Constant Deck and Supply Temperatures

["Michael J. Witte" <mjwitte@xxxxxxxx>]

While the DX coil cannot control itself directly, a gas heating coil can.  For 
this application, delete the FURNACE object and put the gas heating coil 
directly on the branch and specify the coil outlet node to be the Coil Temp 
Setpoint Node.  Use SET POINT MANAGER:SCHEDULED to place the heating and 
cooling setpoints at the respective outlet nodes.

I have made a note to make sure that the I/O ref explains which coils can go 
directly on a branch, which need a controller, and which need to be contained 
inside a parent object.
